3 Claims. (Cl. 126-42) This invention relates to gas ranges and moreparticularly to a safety valve whereby the valves are automaticallyclosed through the operation of a cover plate or safety door whichconceals the valve handles and manifold when the stove is not in use. V

A further feature of the invention resides in the adaption of the valveand manifold concealing device as an extension shelf for the cookingWith the device as covered by the present invention as applied to gasstoves and ranges, the valves are not only concealed when the stove isnot in use, but the safety door or cover, when closing engages and movesthe handles from an on or open position, to a completely closed or "011position. In brief, closing the door of the valve and manifoldcompartment compels the actuation of the valve handles from their opento their fully closed position.

In the drawings, 1

Figure 1 is a perspective view of the upper portionof a gas rangeembodying one form of this invention and showing the safety door closed.

Figure 2 is a similar view illustrating the cover of the valvecompartment raised to form an extension shelf; and afford access to thevalve handles Figure 3 is a section taken through the upper frontportion of the stove substantially on the line 33'of Figure 2, butillustrating the safety door midway between j its full-open andfullclosed position, and engaging the valve handle to move it to itsclosed position as illustrated in dotted lines.

Figure 4 is a view similar to Figure 1, but illustrating a modified formof the invention.

Figure 5 illustrates the stove shown in Figure 4, with the cover plateor safety door raised, and

Figure 6 is a sectional view through the stove on the line 6-6 of Figure4.

Referring more particularly to the drawings, and at present to Figures1, 2 and 3, the numeral 1 designates generally a gas range having anoven closed by a flush door 2, controlled by a handle 3, and an upperburner and valve compartment 4, said range having the usual cooking top5, the compartment 4 being also provided with the usual sliding drip-pan6.

At its upper portion, the front wall 7 which is provided with arectangular opening 8 which affords access to the valve, is upwardly andrearwardly curved substantially in the arc of a circle, and forms a hood9 which not only coversithe manifold, but also cooperates with themovable safety door or cover plate 14 to completely house the valveparts.

The gas manifold 10 shown in Figure 3 supports a plurality of. valves11, each of which is controlto a completely closed position, we providea 7 swinging safety door 14, said door being provided at its upperportion, at each end thereof with a pair of rearwardly directed arms 15,the inner ends being provided by suitable bearings 16 in the upperforward portion of the side walls of the stove, the bearing beingarranged on the axis of the arc of the hood 9, so that the inner upperedge of the swinging door 14 in its movements from the position shown inFigure 1 to that shown in Figure 2, follows the contour of the outerface of said hood, and substantially forms a sealing joint.

When the door 14 is closed, its rear face first engages the outer end ofthe valve handle 12, as shown in Figure 3 in full lines, and then, incontinuing its closing movement, forces said handle downwardly into thedotted line position, and in which position the valve is completelyclosed. The door may be secured in closed position by means of a latch18 cooperating with a keeper 19.

In the construction shown in Figures 4, 5 and 6, wherein a modified formof the invention is illustrated, the body of the stove is substantiallyidentical with that illustrated in the first embodiment. However, in thepresent arrangement, the upper front portion of the stove, above theoven door 2 is provided with an upwardly and rearwardly inclined panel20, said panel being provided with a' plurality of recesses 21 adaptedto receive the valve handles 22. The recesses 21 are of such depth thatthe valve handles when closed will, as shown in Figure 6, be entirelybelow the plane of the outer face of the panel 21, so that, when a door23, comprising space plates 24 and 25, and hinged at 26, is moved toclosed position as shown, the inner face of the cover 23 lies fiatagainst the panel 21. As shown in dotted lines in Figure 6, the cover 23engages rthe outer end of the valve handle in the manner shown in Figure3 and will move it, or in fact any of the handles which happen to be inopen position to the fully closed .full line position as illustrated.

With either of the constructions shown in the two forms, the personoperating the stove will, when she has finished cooking, move the cover14 or 23 from its position shown respectively in Figures 2 and 5 to thatshown in Figures 1 and 4, in which latter positions, the movable doorwill have engaged any valve handle which they happen to have been openand moved it into its completely closed position shown in dotted linesin Figure 3 or full lines in Figure 6.

For the purpose of maintaining the cover 14 in Figs. 1, 2 and 3, orcover 23 in Figures 4, 5 and 6 in raised position as shown by Figures 2and 5 respectively, we provide a brace 30, suitably pivoted at its upperend at 31 to the inner side of the cover, the lower end of the bracebeing partment, a plate provided at the forward end of said compartment,a manifold in said compartment andconcealed by said plate, valves,handles for said valves arranged and movable outwardly and in front ofsaid plate to open and close said valves, 9. safety door on said body,movable over said plate, whereby when said door is closed it will engageand automatically move and close said valve handles within saidcompartment in said recesses and movable beyond the front plane of saidclosure plate to open the valves, a

safety cover mounted on said body and movable to cover and uncover saidplate, said cover being adapted to engage said handles when the latterextend beyond the plane of the front face of said plate andautomatically move them into said recesses to close the valves.

3. In a gas range, a range body having a burner top, an uppercompartment, a front frame for said compartment, a manifold and valveswithin said compartment, handles for said valves movable beyond thefront plane of said compartment, and a safety door hingedly secured tosaid frame along its upper portion and movable into the plane of theburner top when in open position, and engageable with the valve handleswhen moved to closed position.
